I understand Matt's issue with the model-specific decals. I put my California spec 1985 label next to Nakman's for his 1987. The labels are substantially the same, but do have some differences. These difference seem to be related to different/changing emissions laws rather than physical...
For me, I would probably keep a fresh version in my glove box or center console. I know it probably not your thing, but I could see something larger (9x6"?) on card stock or plastic or maybe even a flexible magnet. Other than the OEM aesthetic, having a small sticker in a fixed location...
Here are some better pictures from my 1985. The vacuum routing diagram doesn’t have any identifier except 2F and USA. The other emissions sticker says it is California spec for 1985
It is on the right side inner fender. There are a bunch of ac hoses and wires (fusible link, etc) that obscure a good picture. And yes there is no indication of which version it is.
I’m busy tomorrow but I’ll try to get a better picture on sunday.
For what it is worth, I found this in my microfiche file. I'm surprised there are so may different variations. I have a california spec (I think) 1985 and I'll grab a photo of the plate later today.
Hey Matt: this exhaust kit is great. Do you have something similar for the manifold to EGR pipe connection? That seems to be a source of frustration for me.
